Economic Load Dispatch Using PSO

Nowadays, electrical energy is playing vital role in human life. The economic operation of the power system is always desirable and this can be achieved by economic load dispatch. The economic load dispatch means allocating the power to different generating units to minimize or reduce the total fuel cost satisfying the different power system constraints. The main purpose of economic load dispatch (ELD) is to allocate the total power at generating units to meet total load demand with minimum operational cost fulfilling all operational obstacles (constraints). For optimal dispatch of power, different evolutionary optimization techniques are being used like CSO, PSO, etc. In this paper, PSO has been implemented on MATLAB to minimize the total cost for 3-unit and 6-unit systems and the results are compared with CSO and other evolutionary optimization techniques for different power demands.
